Usually they're paid to do good reviews. When you aren't paying them, I guess you have to settle for what you get.
That's as maybe.. but it kinda implies that they're incapable of being accurate if there's no money involved. Heck... if I played some game I'd never played before (lets say Eve for example) and I was writing an unpaid review of my starting moments in-game... I'm fairly sure I could get the terminology right.
If it's going to print, I doubt an extra half an hour to check the accuracy of the terms is going to kill anyone.
That said.. whatever, this kind of thing really doesn't affect me that much.
